LUBRICATING MEANS FOR ROLLER-PINIONS.

Application led March 1,

- To all lwhom t may concern.'

Be it known that I, JOHN M. KROYER, a citizen of the United States, residing at Stockton, in the county of San. Joaquin, State of California, have invented certain new and liseful Improvements in Lubricating Means for Roller-Pinions; and I do declare the following to be a full, clear,- and exact description of the same, reference be* ing ,had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to an improved means of lubrication for the teeth of roller pinions, namely, that class of pinions, the teeth of which are constructed by using a turnable roller mountedy upon a stationary pin. By the use of my improved lubricating means all the teeth of thepinion may be lubricated simultaneously from one grease cup thus eliminating the wasting of the grease as well as saving the time of the operator and also at the same time applying the grease where it will do the most good. The

:bearing surface between the roller and the pinion will also be kept clean and free from dirt since in my improved means the grease is applied to the center of the bearing and will at all times be forced to work toward the end ofthe roller thereby keeping a new clean supply near the center.

A further object of the invention' 1s to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of the parts as will fully appear 'by a perusal of the following specification and claim.

Inthefdrawings similar characters of reference indicate corresponding parts in the views. 4

Referring now characters of reference on the drawings the numeral 1 indicates a` shaft and rigidly mounted thereon by means of akey 2 I have provided a hub member 3 having outwardly projecting anges as at 4 and 5.

The other ends of the pins 6 will pass through holes 9 in the flange 4 and have nuts 10 screwed thereon which will bear against spring washers 11. Mounted.

The lubricating means consists of a grease cup 1 3 screwed into the end of the shaft 1. Leading from this grease cup 13 through the shaft 1 is a passageway 14 extending will be the turnable rollapproximately the length of the pinion hub and then leading from this passageway at right angles thereto is another passageway 15 communicating with a halfv round groove 16 cut into the inner surface o f the pinion hub and continuing the full circumference` thereof. Projecting radially through the center point of each pin 6 I have'rthen drilled a hole17 down to the groove 16.

Each pin 6 I have provided with an opening,

as at 18, which will, upon inserting the pin between the flanges 4 and 5, come into comof a p ug 21 toprevent the escape of any.

grease therefrom. l'Ihe continued passageway, as at 17, will not have to be plugged as the stationary pin 6 will efectua'lly close the same. When desiring'to lubricate the rollers it will only be necessary to operate the grease cup 13 which will force the grease passageway 2O at the center of through the :passageways to the center .hearing'points of the rollers. From the foregoing description it will readily be seen that I have produced such a device assubstantilally fulfils the objects of' the invention as set forth herein.

While this specification sets forthin demorel particularlyto the-tail the present 'and preferred construction of the device, still -inp'ractice such deviations from such detail may ybe resorted to as Kdo not form a departure from the spiritfofrthe `4 invention as defined by thev appended claim.

Having thus described my'inventionwhat 'I' I claim as new and useful*v desirev to se.
